I am selling this because it was not compatible with my new place. I used it for about a year. It has been initialized, and I have confirmed that it enters pairing mode when batteries are inserted. The firmware has also been updated to the latest version. *Requires two CR123A batteries. The included parts are as shown in the photos. The adhesive surface has been cleaned with sticker remover. Please understand that this is a used item. Please follow the app instructions for setup. - Brand: SwitchBot - Model Name: SwitchBot Lock - Included Accessories: Mounting parts - Color: Black Thank you for looking.
